Skeeter... if you're here to make money, you might as well just delete your account now.
As Marioh said, this is a GAME WEBSITE not a GAMBLING WEBSITE. People come here to play golf, not win money. WGT instituted the MPC for credits because we, the players, were screaming at them to let us wager between ourselves.
Let's look at TWO.... you spend REAL money there and what do you get in return... attributes to increase your golfers abilities.... don't see anyone crying about that, do you? They charge money up front. No cashout at the end when your cartoon golfer is all God-like.
Yes, WGT wants you to spend real, hard-earned cash to get better stuff IF YOU WANT IT. Once you've spent it, it's theirs to do with as they please. There is nothing here that says they HAVE to give it back to you. Sure, they offer real cash prizes (or values) for doing well, and sure, you will have to upgrade your equipment to even sniff those, but that's a tried and true business model.
If you want the big prize, you gotta race the big boys. If you can't do it, it's not their fault. They give everyone the same opportunity.
Again, the game is free. Once you have spent money here, that money belongs to WGT to do with as they please. The credits you buy are "house-money" good only in this house.
And this 'house' has a door.
And it's unlocked.
